On multiple occasions when driving the audi q5 the pre-sense engages inappropriately (no trigger) resulting in an immediate and harsh braking of the car to a complete stop. in traffic, this poses a significant risk of a crash resulting in damage and potential bodily injury. the audi pre-sense is designed to stop a car from an imminent crash, however an apparent flaw in the technology engages the pre-sense without totally unnecessarily (no cross traffic, at least 10 feet from a bush or other object). not only does the unexpected and unnecessary hard auto-braking add wear and tear to the brakes and suspension, it poses a real risk of an accident as other drivers do not expect the sudden and unnecessary braking. this happens intermittently without a pattern in dry and wet weather on a flat surface or an incline. always occurs when in reverse.
While driving down the expressway in chicago, transmission, and all safety features completely shut off. pressing on accelerator had no effect, and with limited steering was able to pull to roadside barely missing high-speed traffic. expressway roadside is narrow, so was nearly hit by many cars while waiting for tow service. car would not restart and with full electronic transmission, no ability to put into neutral. audi roadside assistance did not provide timely tow service. extremely dangerous and unsafe.
